Boston Portable Power Supply BESS

What is battery energy storage system (BESS)?

What is BESS? The Battery Energy Storage System (BESS) is an advanced technology that stores excess electrical energy in rechargeable batteries and releases it when required. As a smart energy storage solution, BESS is designed to replace diesel generators.

What type of battery does Bess use?

The most commonly used battery types in BESS include: Lithium-ion (Li-ion): Known for its high energy density, commonly used in electric vehicles and grid energy storage. Lead-acid battery: More affordable, but with lower efficiency and a shorter lifespan. Flow battery (e.g., all-vanadium flow battery): Ideal for long-term energy storage.

What is Bess & how does it work?

BESS stores surplus energy generated from renewable energy sources such as wind and solar. This stored energy can be released when demand exceeds production. This technology plays a crucial role in integrating renewable energy into our electricity grids by helping to address the inherent supply-demand imbalance of intermittent renewable sources. 2.

Is ISO New England planning a 300MW Bess in Boston?

System operator ISO New England has given the go-ahead for a 300MW/1,200MWh indoor BESS located in Boston, Massachusetts under development by developer and IPP Flatiron Energy. ISO New England approved a proposed plan application associated with the project in the form of a letter published on the system operator’s website on 6 January, 2025.
